Mean Absolute Error (MAE) is a measure of the average magnitude of errors between predicted values and actual values in a dataset, without considering their direction. It provides a clear insight into how well a model's predictions align with real-world observations, making it particularly useful for assessing forecasting accuracy in time series analysis. MAE is calculated by taking the average of the absolute differences between predicted and observed values, and it helps to identify the overall performance of predictive models in capturing time series components.
congrats on reading the definition of Mean Absolute Error (MAE). now let's actually learn it.
